Torcs

The Open Racing Car Simulator. TORCS is a highly portable multi platform car racing simulation. It is used as ordinary car racing game, as AI racing game and as research platform. There are various sites on the Internet dedicated to TORCS with additional content (cars, tracks, documentation, patches, etc.)

Torcs isn’t bad, though the graphics aren’t the best they’re decent. It’s your average racing sim, IMO. Speed-Dreams has much nicer graphics but is essentially the same game, though I find the cars harder to control in Speed-Dreams.
